<p>Hello. I want to be of help to the Rust community. Any small issues regarding GAT or const generics that I can help with?</p>

<p>Hey <span class="user-mention" data-user-id="303115">@Quy Nguyen</span>,</p>
<p>I can give you some pointers if you want to help out with const generics.<br>
We recently landed both <a href="https://github.com/rust-lang/rust/issues/70107">#70107</a> and <a href="https://github.com/rust-lang/rust/issues/71973">#71973</a>, which probably caused quite a few issues with the <code>F-const_generics</code> label to be outdated. (<a href="https://github.com/rust-lang/rust/issues?q=is%3Aopen+is%3Aissue+label%3AF-const_generics+">https://github.com/rust-lang/rust/issues?q=is%3Aopen+is%3Aissue+label%3AF-const_generics+</a>)</p>

<p>An example is <a href="https://github.com/rust-lang/rust/issues/67185">https://github.com/rust-lang/rust/issues/67185</a>, which now successfully compiles (even without the <code>#[feature(const_generics)]</code> label</p>

<p>It would be really helpful if you either check if these issues are still relevant, and if not, add a regression test to <code>src/test/ui/const-generics</code></p>

<p>I am currently looking for issues which might be a good starting point if you want to get a bit more involved/hack on the compiler itself</p>

<p>hm, you might try and improve <a href="https://github.com/rust-lang/rust/blob/ccac43b86b559e01fa71179af1a838ab94559c75/src/librustc_infer/infer/error_reporting/need_type_info.rs#L537">https://github.com/rust-lang/rust/blob/ccac43b86b559e01fa71179af1a838ab94559c75/src/librustc_infer/infer/error_reporting/need_type_info.rs#L537</a><br>
<code>need_type_info_err_const</code> by mostly copying what <code>need_type_info_err</code> does for types.</p>
<p>Or you might look at the issues mentioned in <a href="https://github.com/rust-lang/rust/issues/68400#issuecomment-621466491">https://github.com/rust-lang/rust/issues/68400#issuecomment-621466491</a>, even if it is slightly outdated</p>

<p>I do feel like most const generics issues aren't that friendly for newcomers at the moment, which is somewhat unfortunate.<br>
If you are interested in working on other areas as well, consider asking <span class="user-mention silent" data-user-id="120823">DPC</span> for recommendations or look at open issues tagged with <code>E-easy</code>.</p>
